The Real Exchange Rate and Economic Growth

Abstract: I show that undervaluation of the currency (a high real exchange rate) stimulates economic growth. This is true particularly for developing countries. This finding is robust to using different measures of the real exchange rate and different estimation techniques. I also provide some evidence that the operative channel is the size of the tradable sector (especially industry). These results suggest that tradables suffer disproportionately from the government or market failures that keep poor countries from converging toward countries with higher incomes. I present two categories of explanations for why this may be so, the first focusing on institutional weaknesses, and the second on product-market failures. A formal model elucidates the linkages between the real exchange rate and the rate of economic growth.

Remittances and the Dutch Disease

Abstract: Using data for El Salvador and Bayesian techniques, we develop and estimate a two-sector dynamic stochastic general equilibrium model to analyze the effects of remittances in emerging market economies. We focus our study on whether rising levels of remittances result in the Dutch disease phenomenon in recipient economies. We find that, whether altruistically motivated or otherwise, an increase in remittances flows leads to a decline in labor supply and an increase in consumption demand that is biased toward nontradables. The increase in demand for nontradables, coupled with higher production costs, results in an increase in the relative price of nontradables, which further causes the real exchange rate to appreciate. The higher nontradable prices serve as an incentive for an expansion of that sector, culminating in reallocation of labor away from the tradable sector. This resource reallocation effect eventually causes a contraction of the tradable sector. A vector autoregression analysis provides results that are consistent with the dynamics of the model.

Why Did Financial Globalization Disappoint

Abstract: The stylized fact that there is no correlation between long-run economic growth and financial globalization has spawned a recent literature that purports to provide newer evidence and arguments in favor of financial globalization. We review this literature and find it unconvincing. The underlying assumptions in this literature are that developing countries are savings-constrained; that access to foreign finance alleviates this to boost investment and long-run growth; and that insofar as there are problems with financial globalization, these can be remedied through deep institutional reforms. In contrast, we argue that developing economies are as or more likely to be investment- than savings-constrained and that the effect of foreign finance is often to aggravate this investment constraint by appreciating the real exchange rate and reducing profitability and investment opportunities in the traded goods sector, which have adverse long-run growth consequences. It is time for a new paradigm on financial globalization, and one that recognizes that more is not necessarily better. Depending on context and country, the appropriate role of policy will be as often to stem the tide of capital inflows as to encourage them. Policymakers who view their challenges exclusively from the latter perspective risk getting it badly wrong.

Out-of-Sample Exchange Rate Predictability with Taylor Rule Fundamentals

Abstract: An extensive literature that studied the performance of empirical exchange rate models following Meese and Rogoff's (1983a) seminal paper has not convincingly found evidence of out-of-sample exchange rate predictability. This paper extends the conventional set of models of exchange rate determination by investigating predictability of models that incorporate Taylor rule fundamentals. We find evidence of short term predictability for 11 out of 12 currencies vis-a-vis the U.S. dollar over the post-Bretton Woods float, with the strongest evidence coming from specifications that incorporate heterogeneous coefficients and interest rate smoothing. The evidence of predictability is much stronger with Taylor rule models than with conventional interest rate, purchasing power parity, or monetary models.

Global imbalances and the financial crisis: products of common causes

Abstract: This paper makes a case that the global imbalances of the 2000s and the recent global financial crisis are intimately connected. Both have their origins in economic policies followed in a number of countries in the 2000s and in distortions that influenced the transmission of these policies through U.S. and ultimately through global financial markets. In the U.S., the interaction among the Fed’s monetary stance, global real interest rates, credit market distortions, and financial innovation created the toxic mix of conditions making the U.S. the epicenter of the global financial crisis. Outside the U.S., exchange rate and other economic policies followed by emerging markets such as China contributed to the United States’ ability to borrow cheaply abroad and thereby finance its unsustainable housing bubble.

China's current account and exchange rate

Abstract: We examine whether the Chinese exchange rate is misaligned and how Chinese trade flows respond to the exchange rate and to economic activity. We find, first, that the Chinese currency, the renminbi (RMB), is substantially below the value predicted by estimates based upon a cross-country sample, when using the 2006 vintage of the World Development Indicators. The economic magnitude of the mis-alignment is substantial - on the order of 50 percent in log terms. However, the misalignment is typically not statistically significant, in the sense of being more than two standard errors away from the conditional mean. Moreover, this finding disappears completely when using the most recent 2008 vintage of data; then the estimated undervaluation is on the order of 10 percent. Second, we find that Chinese multilateral trade flows respond to relative prices - as represented by a trade weighted exchange rate - but the relationship is not always precisely estimated. In addition, the direction of the effects is sometimes different from what is expected a priori. For instance, Chinese ordinary imports actually rise in response to a RMB depreciation; however, Chinese exports appear to respond to RMB depreciation in the expected manner, as long as a supply variable is included. In that sense, Chinese trade is not exceptional. Furthermore, Chinese trade with the United States appears to behave in a standard manner - especially after the expansion in the Chinese manufacturing capital stock is accounted for. Thus, the China-US trade balance should respond to real exchange rate and relative income movements in the anticipated manner. However, in neither the case of multilateral nor bilateral trade flows should one expect quantitatively large effects arising from exchange rate changes. And, of course, these results are not informative with regard to the question of how a change in the RMB/USD exchange rate would affect the overall US trade deficit.

The Slide to Protectionism in the Great Depression: Who Succumbed and Why?

Abstract: The Great Depression was marked by a severe outbreak of protectionist trade policies But contrary to the presumption that all countries scrambled to raise trade barriers, there was substantial cross-country variation in the movement to protectionism Specifically, countries that remained on the gold standard resorted to tariffs, import quotas, and exchange controls to a greater extent than countries that went off gold Gold standard countries chose to maintain their fixed exchange rate and reduce spending on imports rather than allow their currency to depreciate Trade protection in the 1930s was less an instance of special interest politics than second-best macroeconomic policy when monetary and fiscal policies were constrained

Resolving the Exposure Puzzle: The Many Facets of Exchange Rate Exposure

Abstract: Theory predicts sizeable exchange rate (FX) exposure for many firms. However, empirical research has not documented such exposures. To examine this discrepancy, we extend prior theoretical results to model a global firm’s FX exposure and show empirically that firms pass through part of currency changes to customers and utilize both operational and financial hedges. For a typical sample firm, pass-through and operational hedging each reduce exposure by 10% to 15%. Financial hedging with foreign debt, and to a lesser extent FX derivatives, decreases exposure by about 40%. The combination of these factors reduces FX exposures to observed levels.

Cross-Country Causes and Consequences of the 2008 Crisis: International Linkages and American Exposure

Abstract: This paper models the causes of the 2008 financial crisis together with its manifestations, using a Multiple Indicator Multiple Cause (MIMIC) model Our analysis is conducted on a cross-section of 85 countries; we focus on international linkages that may have allowed the crisis to spread across countries Our model of the cross-country incidence of the crisis combines 2008 changes in real GDP, the stock market, country credit ratings, and the exchange rate We explore the linkages between these manifestations of the crisis and a number of its possible causes from 2006 and earlier The causes we consider are both national (such as equity market run-ups that preceded the crisis) and, critically, international financial and real linkages between countries and the epicenter of the crisis We consider the United States to be the most natural origin of the 2008 crisis, though we also consider six alternative sources of the crisis A country holding American securities that deteriorate in value is exposed to an American crisis through a financial channel Similarly, a country which exports to the United States is exposed to an American downturn through a real channel Despite the fact that we use a wide number of possible causes in a flexible statistical framework, we are unable to find strong evidence that international linkages can be clearly associated with the incidence of the crisis In particular, countries heavily exposed to either American assets or trade seem to behave little differently than other countries; if anything, countries seem to have benefited slightly from American exposure

The Forward Market in Emerging Currencies: Less Biased Than in Major Currencies

Abstract: Many studies have replicated the finding that the forward rate is a biased predictor of the future change in the spot exchange rate. Usually the forward discount actually points in the wrong direction. But, at least until recently, those studies applied only to advanced economies and major currencies. We apply the same tests to a sample of 14 emerging market currencies. We find a smaller bias than for advanced country currencies. The coefficient is on average positive, i.e., the forward discount at least points in the right direction. It is never significantly less than zero. To us this suggests that a time-varying exchange risk premium may not be the explanation for traditional findings of bias. The reasoning is that emerging markets are probably riskier; yet we find that the bias in their forward rates is smaller. Emerging market currencies probably have more easily-identified trends of depreciation than currencies of advanced countries.

Are Free Trade Agreements Contagious

Abstract: This paper presents empirical evidence on the extent to which FTAs are "contagious", using empirical techniques inspired by the study of contagion in exchange rate crises Applying a series of different econometric techniques, it tests the null hypothesis that the signing of an FTA between one nation's trade partners has no affect on the probability of the nation signing a new FTA The hypothesis is tested against other political, economical and geographical determinants of the FTA formation previously stated in the literature, finding evidence that the contagion phenomenon is present in different specifications and samples

An Economic Evaluation of Empirical Exchange Rate Models

Abstract: This paper provides a comprehensive evaluation of the short-horizon predictive ability of economic fundamentals and forward premiums on monthly exchange-rate returns in a framework that allows for volatility timing. We implement Bayesian methods for estimation and ranking of a set of empirical exchange rate models, and construct combined forecasts based on Bayesian model averaging. More importantly, we assess the economic value of the in-sample and out-of-sample forecasting power of the empirical models, and find two key results: (1) a risk-averse investor will pay a high performance fee to switch from a dynamic portfolio strategy based on the random walk model to one that conditions on the forward premium with stochastic volatility innovations and (2) strategies based on combined forecasts yield large economic gains over the random walk benchmark. These two results are robust to reasonably high transaction costs.

What Explains Global Exchange Rate Movements during the Financial Crisis

Abstract: A striking and unexpected feature of the financial crisis has been the sharp appreciation of the US dollar against virtually all currencies globally. The paper finds that negative US-specific macroeconomic shocks during the crisis have triggered a significant strengthening of the US dollar, rather than a weakening. Macroeconomic fundamentals and financial exposure of individual countries are found to have played a key role in the transmission process of US shocks: in particular countries with low FX reserves, weak current account positions and high direct financial exposure vis-a-vis the United States have experienced substantially larger currency depreciations during the crisis overall, and to US shocks in particular.

China's Current Account and Exchange Rate

Abstract: We examine whether the Chinese exchange rate is misaligned and how Chinese trade flows respond to the exchange rate and to economic activity. We find, first, that the Chinese currency, the renminbi (RMB), is substantially below the value predicted by estimates based upon a cross-country sample, when using the 2006 vintage of the World Development Indicators. The economic magnitude of the misalignment is substantial iV on the order of 50 percent in log terms. However, the misalignment is typically not statistically significant, in the sense of being more than two standard errors away from the conditional mean. However, this finding disappears completely when using the most recent 2008 vintage of data; then the estimated undervaluation is on the order of 10 percent. Second, we find that Chinese multilateral trade flows respond to relative prices iV as represented by a trade weighted exchange rate iV but the relationship is not always precisely estimated. In addition, the direction of the effects is sometimes different from what is expected a priori. For instance, Chinese ordinary imports actually rise in response to a RMB depreciation; however, Chinese exports appear to respond to RMB depreciation in the expected manner, as long as a supply variable is included. In that sense, Chinese trade is not exceptional. Furthermore, Chinese trade with the United States appears to behave in a standard manner iV especially after the expansion in the Chinese manufacturing capital stock is accounted for. Thus, the China-US trade balance should respond to real exchange rate and relative income movements in the anticipated manner. However, in neither the case of multilateral nor bilateral trade flows should one expect quantitatively large effects arising from exchange rate changes. And, of course, these results are not informative with regard to the question of how a change in the RMB/USD exchange rate would affect the overall US trade deficit. Finally, we stress the fact that considerable uncertainty surrounds both our estimates of RMB misalignment and the responsiveness of trade flows to movements in exchange rates and output levels. In particular, the results for trade elasticities are sensitive to econometric specification, accounting for supply effects, and for the inclusion of time trends.

What Lies Beneath the Euro's Effect on Financial Integration? Currency Risk, Legal Harmonization, or Trade?

Abstract: Although recent research shows that the euro has spurred cross-border financial integration, the exact mechanisms remain unknown We investigate the underlying channels of the euro’s effect on financial integration using data on bilateral banking linkages among twenty industrial countries in the past thirty years We also construct a dataset that records the timing of legislative-regulatory harmonization policies in financial services across the European Union We find that the euro’s impact on financial integration is primarily driven by eliminating the currency risk Legislative-regulatory convergence has also contributed to the spur of cross-border financial transactions Trade in goods, while highly correlated with bilateral financial activities, does not play a key role in explaining the euro’s positive effect on financial integration JEL Classification: F1, F3, G2, K0

Cross-Country Causes and Consequences of the 2008 Crisis: Early Warning

Abstract: This paper models the causes of the 2008 financial crisis together with its manifestations, using a Multiple Indicator Multiple Cause (MIMIC) model. Our analysis is conducted on a cross-section of 107 countries; we focus on national causes and consequences of the crisis, ignoring cross-country contagion effects. Our model of the incidence of the crisis combines 2008 changes in real GDP, the stock market, country credit ratings, and the exchange rate. We explore the linkages between these manifestations of the crisis and a number of its possible causes from 2006 and earlier. We include over sixty potential causes of the crisis, covering such categories as: financial system policies and conditions; asset price appreciation in real estate and equity markets; international imbalances and foreign reserve adequacy; macroeconomic policies; and institutional and geographic features. Despite the fact that we use a wide number of possible causes in a flexible statistical framework, we are unable to link most of the commonly-cited causes of the crisis to its incidence across countries. This negative finding in the cross-section makes us skeptical of the accuracy of early warning systems of potential crises, which must also predict their timing.

The Transmission of International Shocks: A Factor‐Augmented VAR Approach

Abstract: The empirical literature on the transmission of international shocks is based on small scale VARs. In this paper, we use a large panel of data for 17 industrialized countries to investigate the international transmission mechanism, and revisit the anomalies that arise in the empirical literature. We propose a Factor Augmented VAR (FAVAR) that extends the model in Bernanke, Boivin and Eliasz (2003) to the open economy. The main results can be summarized as follows. First, the dynamic effects on the UK economy of an unanticipated fall of short-term interest rates in the rest of the world are: real house price inflation, investment, GDP and consumption growth peak after one year; wages peak after two years; CPI and GDP deflator inflation peak during the third year. Second, a positive international supply shock makes the distribution of the components of the UK consumption deflator negatively skewed. Third, in response to a domestic monetary shock, we find no evidence of the exchange rate and liquidity puzzles, and little evidence of the forward discount and price anomalies.

Impact of Oil Price Shock and Exchange Rate Volatility on Economic Growth in Nigeria: An Empirical Investigation

Abstract: This paper seeks to assess the impact of oil price shock and real exchange rate volatility on real economic growth in Nigeria on the basis of quarterly data from 1986Q1 to 2007Q4. The empirical analysis starts by analyzing the time series properties of the data which is followed by examining the nature of causality among the variables. Furthermore, the Johansen VAR-based cointegration technique is applied to examine the sensitivity of real economic growth to changes in oil prices and real exchange rate volatility in the long-run while the short run dynamics was checked using a vector error correction model. Results from ADF and PP tests show evidence of unit root in the data and Granger pairwise causality test revealed unidirectional causality from oil prices to real GDP and bidirectional causality from real exchange rate to real GDP and vice versa. Findings further show that oil price shock and appreciation in the level of exchange rate exert positive impact on real economic growth in Nigeria. The paper recommends greater diversification of the economy through investment in key productive sectors of the economy to guard against the vicissitude of oil price shock and exchange rate volatility.

Exchange Rates and Fundamentals: Footloose or Evolving Relationship?

Abstract: Using novel real-time data on a broad set of economic fundamentals for five major US dollar exchange rates over the recent float, we employ a predictive procedure that allows the relationship between exchange rates and fundamentals to evolve over time in a very general fashion. Our key findings are that: (i) the well-documented weak out-of-sample predictive ability of exchange rate models may be caused by poor performance of model-selection criteria, rather than lack of information content in the fundamentals; (ii) the difficulty of selecting the best predictive model is largely due to frequent shifts in the set of fundamentals driving exchange rates, which can be interpreted as reflecting swings in market expectations over time. However, the strength of the link between exchange rates and fundamentals is different across currencies.

Asset Prices, Exchange Rates and the Current Account

Abstract: This paper analyses the role of asset prices in comparison to other factors, in particular exchange rates, as a driver of the US trade balance. It employs a Bayesian structural VAR model that requires imposing only a minimum of economically meaningful sign restrictions. We find that equity market shocks and housing price shocks have been major determinants of the US current account in the past, accounting for up to 32% of the movements of the US trade balance at a horizon of 20 quarters. By contrast, shocks to the real exchange rate have been much less relevant, explaining less than 7% and exerting a more temporary effect on the US trade balance. Our findings suggest that sizeable exchange rate movements may not necessarily be a key element of an adjustment of today's large current account imbalances, and that in particular relative global asset price changes could be a more potent source of adjustment.

Capital Inflows: Macroeconomic Implications and Policy Responses

Abstract: This paper examines the macroeconomic implications of, and policy responses to surges in private capital inflows across a large group of emerging and advanced economies. In particular, we identify 109 episodes of large net private capital inflows to 52 countries over 1987-2007. Episodes of large capital inflows are often associated with real exchange rate appreciations and deteriorating current account balances. More importantly, such episodes tend to be accompanied by an acceleration of GDP growth, but afterwards growth has often dropped significantly. A comprehensive assessment of various policy responses to the large inflow episodes leads to three major conclusions. First, keeping public expenditure growth steady during episodes can help limit real currency appreciation and foster better growth outcomes in their aftermath. Second, resisting nominal exchange rate appreciation through sterilized intervention is likely to be ineffective when the influx of capital is persistent. Third, tightening capital controls has not in general been associated with better outcomes.

Currency Carry Trade Regimes: Beyond the Fama Regression

Abstract: We examine the factors that account for the returns on currency carry trade strategies. Using a dataset of daily returns spanning 18 years for 5 different long - short currency carry portfolios, we first document a robust empirical relationship between carry trade excess returns and exchange rate volatility, both realized and implied. Specifically, we extend and refine the results in Bhansali (2007) by documenting that currency carry trade strategies implemented with forward contracts have payoff and risk characteristics that are similar to those of currency option strategies that sell out of the money puts on high interest rates currencies. Both strategies have the feature of collecting premiums or carry to generate persistent excess returns that unwind sharply resulting in losses when actual and implied volatility rise. We next also document significant volatility regime sensitivity for Fama regressions estimated over low and high volatility periods. Specifically we find that the well known result that a regression of the realized exchange rate depreciation on the lagged interest rate differential produces a negative slope coefficient (instead of unity as predicted by uncovered interest parity) is an artifact of the volatility regime: when volatility is in the top quartile, the Fama regression produces a positive coefficient that is greater than unity. The third section of the paper documents the existence of an intuitive and significant co-movement between currency risk premium and risk premia in yield curve factors that drive bond yields in the countries that comprise carry trade pairs. We show that yield curve level factors are positively correlated with carry trade excess returns while yield curve slope factors are negatively correlated with carry trade excess returns. Importantly, we show that this correlation is robust to the current crisis and to the inclusion of equity volatility in the model. What distinguishes carry trade returns in the current crisis from non crisis periods is not changed loading on yield curve factors but a much larger loading on the equity factor.
